In
the Abhidhamma Vibhanga Pali (284), these four kinds of Brahmavihara
are stated to be Appamanna. In the Mahâvâ Mahâ
Govinda Sutta, it has been called 'Brahmacariya'. It means the
practice of the life of holiness led by the sanctified, or in other
words, the practice of Appamanna - the perfect exercise of the
qualities of loving-kindness or friendliness, compassion, goodwill,
and equanimity (metta, karuna, mudita and upekkha). The
term "Brahmacora Dhamma" commonly known and spoken in Burmese
language is derived from the Pali word - "Brahmacariya".

When
this "metta" is developed, it must be developed dwelling one's
mind on the pannatta - the manifestation of what is known by
the nomenclature "puggala" (individual) and "sattava" (being).
Hence, there is every likelihood of having a false belief in atta
or Self (attaditthi) with clinging attachment or a notion
that 'an individual', or 'a being' really exists. Such being the case,
the Exalted One has taught the last verse of the Sutta in conclusion
as quoted below, in order to cause to dispel this "attaditthi" which
is likely to occur, and to enable mankind to attain ariya-magga-phala.
